An atom is the most unit of living and nonliving things. answers > > a)basic b)complex c)interesting d)sizeable next question! a is the basic unit of structure and function in living organisms. 1.)cell 2.)tissue 3.)molecule 4.)nucleus last question . the levels of organization within an organism are atom, molecule, tissue, and organ system. l)atomic number; element o)cell; organ v)compound; kidney e)nucleus; membrane

1. basic so you are correct

2. cells

3. cell; organ

Explanation:

1. The atom is actually the smallest and most basic unit of matter. You can say it's essential to all things. Atoms are the smallest particles of matter, but there are lots (and lots) of them. Atoms join together to form molecules.

2.Tissue is the next level of organization after cells. It is a group of similar cells that work together to perform a certain function. Muscle is a type of human tissue. Other examples are connective, epithelial, and nervous tissue. A molecule is formed when two or more atoms are joined together by a chemical bond. Some molecules are made up of multiple atoms of the same element, like oxygen gas, which is made of two oxygen atoms bonded together (O2). Others are combinations of different elements, like water, which is two hydrogen atoms and one oxygen atom (H2O). A molecule with more than one element is an example of a compound. A cell is the basic unit of structure and function in all living organisms. Cells are true bodybuilders! Cells are made of multiple types of molecules. All living things are made of at least one cell. Larger organisms are made of lots of cells. So the answer is cell.

3. You can look at the picture. It is in the order you need.

i need an image of the diagram

the fossil record provides evidence of a common ancestor to many species.
